Why do I get the error "Client denied access due to access control rule" when using the JDBC-ODBC Bridge?

The Easysoft JDBC-ODBC Bridge JDBC driver has attempted to connect to a JDBC-ODBC Bridge server, but there is an access control rule on the server machine that denies client access. Use the JDBC-ODBC Bridge web administration interface to examine the access control rules. Go to:

http://myserver:8031

Then choose Security. The access control rules are defined on this page.
